I-Nickel Alloy Welding Electrode AWS A5.11 ENiCrFe-7 I-Low Hydrogen Nickel Welding Rods, I-Arc Welding Stick

I-Nickel ne-Nickel Alloy Welding Electrode

I-Ni307-7                                                     

I-GB/T ENi6152

I-AWS A5.11 ENCrFe-7

Incazelo: I-Ni307-7 iyi-electrode esekwe ku-nickel ene-low-hydrogen sodium coating.Sebenzisa i-DCEP (i-electrode yamanje eqondilepositive).Inokusebenza okuhle kakhulu kwe-welding enokuvutha kwe-arc okuzinzile, i-spatter encane, ukususa kalula i-slag,kanye ne-weld enhle.Insimbi efakiwe inezinto ezizinzile zemishini kanye nokumelana nokugqwala okuhle ngaphakathiizinga lokushisa eliphezulu oxidizing kanye nomkhathi esinesulfure.

Isicelo: Isetshenziswa kubunjiniyela benuzi, i-sulfuric acid, i-nitric acid ne-hydrogen fluorine imishini yokukhiqiza, efana ne-nickel 690 alloy, ASTM B166, B167, b168, njll., ingasetshenziselwa ukushisela i-nickel-chromium iron nensimbi engagqwali nokugqwala okungaphezulu. -izingqimba ezingazweli ensimbi.

Ukwakheka kwamakhemikhali ensimbi ye-weld(%):

Izici zemishini ye-weld metal:

Okwamanje okunconyiwe:

Isaziso:

1. I-electrode kufanele ibhakwe ihora elingu-1 endaweni engaba ngu-300 ℃ ngaphambi kokusebenza kokushisela;

2. Kubalulekile ukuhlanza okugqwalile, uwoyela, amanzi, nokungcola ezingxenyeni zokushisela ngaphambi kokushisela.Zama ukusebenzisa i-arc emfushane ukushisela.
